DESCRIPTION: \nWinter ecological processes are important drivers of ecosyst
 em  functioning ecosystems. Winter conditions are subject to rapid climate
   change. The potential loss of a longer-lasting snow cover with  implicat
 ions to other ecologically important climate parameters makes  the tempera
 te zone particularly vulnerable to winter climate change.  Trends in the o
 ccurrence of soil frost and snow cover based on climate  data series of 15
 0 German Weather Service stations and regional  statistical climate modell
 ing approaches are presented. Examples from  own experiments indicate the 
 strong and lasting effects of winter  warming pulses on species compositio
 n\, productivity and nutrient  availability. Root injury and mycorrhizal c
 ommunity composition  (ITS-sequencing) have been tested as causal drivers 
 of the observed  effects. A formalized literature search in the ISI-Web of
  Science  finally shows that research on the effects of winter climate cha
 nge is  generally underrepresented. Temperate regions in particular are ra
 rely  studied in this respect\, although the few existing studies imply st
 rong  effects of winter climate change on species ranges\, species  compos
 itions\, phenology\, or frost injury. I conclude by discussing gaps  in cu
 rrent knowledge such as the understanding of the relative effects  of inte
 racting climate parameters\, as well as a stronger consideration  of short
 term events and variability of climatic conditions.\n
